Currency count verifier

ABSTRACT

A machine for verifying the quantity of bills in a stack of bills of the same denomination has a receiving compartment in which the stack of bills to be counted is placed. The bills are removed one at a time from the receiving compartment and are passed through a counting section and elevated up to a discharge compartment. The bills are counted by the actuation of a count switch as they pass through the counting section with the count recorded visually on a counter. The machine is set in operation by the depression of a start switch which will function to carry out the count of the stack of bills only if a stack switch is closed indicating that one or more bills are present in the receiving compartment. The movement of the last bill of the stack out of the receiving compartment will open the stack switch but the circuit to operate the machine will remain energized for a sufficient time to permit the last bill of the stack to be transported to the discharge compartment. Overlapping, folded or double bills which would provide a false count are sensed in the counting section and a warning light alerts the operator to the fact that doubled bills have been counted. The operator must then depress a reset button before the machine can again be operated.

The bills are removed one at a time fromthe receiving compartment and are passed through a counting section andelevated up to a discharge compartment. The bills are counted by theactuation of a count switch as they pass through the counting sectionwith the count recorded visually on a counter. The machine is set inoperation by the depression of a start switch which will function tocarry out the count of the stack of bills only if astack switch isclosed indicating that one or more bills are present in the receivingcompartment. The movement of the last bill of the stack out of thereceiving compartment will open the stack switch but the circuit tooperate the machine will remain energized for a sufficient time topermit the last bill of the stack to be transported to the dischargecompartment. Overlapping, folded or double bills which would provide afalse count are sensed in the counting section and a warning lightalerts the operator to the fact that doubled bills have been counted.The operator must then depress a reset button before the machine canagain be operated.

7 Claims, 6 Drawing Figures PAIENIEI] JAN 2 2 IBM SHEEI 1 BF 3 CURRENCYCOUNT VERIFIER BACKGROUND OF THE INVENTION This invention relates topaper currency handling equipment, and particularly to apparatus forverifying the count of a stack of currency.

Paper currency counters have been proposed and are in use in which billsar removed singly from a stack and pass through a counting section inwhich the bills are individually counted and in which any bills whichoverlap such that a proper count would be impossible are ejected fromthe counting section and not made a part of the actual count of bills.Examples of such equipment are shown in U.S. Pat. No. 2,805,825 issuedSept. 10, 1957 to Julius Jorgensen et al and U.S. Pat. No. 3,214,096issued Oct. 26, 1965 to Arnold R. Buchholz et al. Such currency countingequipment finds particular application in subdividing a quantity ofbills into batches each containing a pre-selected number of bills,although they may also be used to verify the count of a strap of bills.

Bills are commonly deposited in financial institutions in straps whichhave been counted by the depositor and it becomes necessary for thefinicial institution to check the accuracy of the count of the bills inthe strap. As a manual task, this is both time consuming and subject tothe usual human errors. While the aforementioned currency counters maybe used for the verification of the count of a strap of bills, such usedoes not fully take advantage of the versatility of such equipment andthe investment which the equipment represents since they are moresuitably used for the more complex function of subdividing quantities ofbills into batches of predetermined numbers.

Accordingly, what is needed by financial institutions to replace themanual verification of straps of bills is a simple economical apparatusdesigned specifically for that purpose and incorporating features whichare particularly adapted for that purpose. The currency count verifierof this invention meets the requirements of the apparatus designed forthe function of verifying the count of the strap of bills.

SUMMARY OF THE INVENTION The invention comprises a currency countverifier having a receiving compartment, a counting section, and adischarge compartment, with power driven conveying means for removingbills singly from the receiving section and passing them through acounting section, in which the passage of each bill is sensed so thatthe count may be registered, and into the discharge compartment, and inwhich the conveying means is operable only when one or more bills are inplace within the receiving compartment.

The invention further resides in such a currency counter in which theoperation of the conveying means is automatically halted after the lastbill in the stack has been counted and moved into the dischargecompartment.

The invention also resides in a currency count verifier with means fordetecting the passage of overlapping, folded or double bills through thecounting section to alert the operator to a miscount of bills and toprevent the subsequent operation of the conveyor means without prioraction on the part of the operator acknowledging his awareness thatoverlapped, folded or double bills are present.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings,and particularly to FIGS. 1 and 3, the verifier includes a receivingcompartment designated generally by the numeral 10. The receivingcompartment is located at the lower front of the machine and is definedby a pair of space side frames 11 and 12 and a feed runway 13extendingbetween the side frames 11 and 12. The side frames 11 and 12rise vertically from a base' 14. An L-shaped bracket 15 is connectedbelow the front end of the feed runway 13. A pair of spaced runwayadjustment assemblies 16 join the bracket 15 to an upstanding bracket 17mounted to the base 14 and function in a manner described hereafter topermit adjustment of the position of the bracket 15 relative to thebracket 17 against the urging of compression springs 18. The feed runway13 has a forward depending arcuate portion adapted to cooperate with alower bank of feed rollers 19 mounted on a driven shaft 20 joumaled inthe side frames 11 and 12. The arcuate portion of the feed runway 13 isbiased upwardly against the lower feed rollers 19 by a spring 21 theforce of which may be adjusted by an adjusting screw 22. The propercontact between the arcuate portion of the feed runway 13 and the lowerrollers 19 is achieved by adjusting the screw 22 and the assemblies 16.

Upper feed rollers 23 mounted on a driven shaft 24 are disposed aboveand slightly forward of the lower feed rollers 19 and together with thelower feed rollers 19 are adapted to engage the endrnost one of a stackof bills placed on edge in the receiving compartment and urged towardsengagement with the feed rollers 19 and 23 by a bill follower 25.

The bill follower includes a horizontal plate portion 26 adapted to rideover the feed runway 13 and an inclined upright plate portion 27 joinedto the horizontal plate portion 26. A handle 28 is provided centrally ofthe bill follower 25 and the bill follower 25 is connected by links 29to the side frames 11 and 12. Torsion springs 30 urge the links 29 to aforward position to urge the bill follower 25 against the feed rollers19 and 23.

A baffle plate 31 is mounted between the side frames 11 and 12' and hassuitable cutouts so that the peripheries of the upper and lower feedrollers 23 and 19 can extend through the baffle plate 31 and contact theendmost one of a stack of bills. The baffle plate 31 also has a centralcutout which accommodates a switch actuator 32 pivoted on a bracket 33which also mounts a normally open, spring loaded stack sensing switch34. The switch actuator 32, under the urgings of the switch 34, normallyprojects through and beyond the baffle plate 31 into a recess providedtherefor in the bill follower 25 (see FIG. 3). When one or more billsare disposed on the feed runway 13 between the bill follower 25 and thefeed rollers 19 and 23, the switch actuator 32 is pivoted in acounterclockwise direction as viewed in FIG. 3 to actuate the stacksensing switch 34.

The shafts 20and 24 mounting the feed rollers 19 and 23 are driven by anelectric motor 35 in a known manner through a suitable arrangment ofbelts, pulleys and gearing so that the lower feed rollers 19 are drivenat a greater speed than the upper feed roller 23. The result is that thebills are accelerated by the lower feed rollers 19 to have a preceedingbill clear the upper feed rollers 23 before the succeeding bill isengaged by the upper feed rollers. The bills, after being removed fromthe stack, are transported by the lower feed rollers 19 to a countingsection defined by a central runway 36 extending between the side frames11 and 12.

Within the counting section is a driven shaft 37 which mounts a seriesof spaced conveyor rollers 38 and pulleys 39. The pulleys 39 engageendless belts 40 which are also engaged about upper pulleys 41 mountedon a shaft 42 disposed above the end of the central runway 36. Theconveyor rollers 38 and lower pulleys 39 are spaced from the lower feedrollers 19 a distance which is less than the width of a bill so that abill which is moved onto the central runway 36 will be engaged betweenthe conveyor rollers 38 and belts 40 and the runway 36 before leaving elower feed rollers 19. A deflector plate 43 is spaced above andparallels the runway 36 between the lower feed rollers 19 and theconveyor rollers 38 and pulleys 39 to strip bills from the lower feedrollers 19 and direct all bills to the conveyor rollers 38 and belts 40.

The conveyor rollers 38 both convey the bills over the central runway 36and maintain the bills taut in a lengthwise direction as they passbeneath the shaft 37. The belts 40 both convey the bills beneath theshaft 37 and elevate the bills to a discharge compartment, identifiedgenerally by the numeral 44. The belts 40 are deflected as they passover the upper end of the central runway 36 so as to pinch the billsbetween the belts 40 and the runway 36. The discharge compartment 44 isdefined by a discharge runway 45 also disposed between the side framesll and 12. The discharge runway 45 includes a discharge bill follower 46having an inclined upright position 47 connected by ears 48 to pivots 49on the side frames 11 and 12, and the bill follower 46 is urged to thereceiving position shown in FIG. 3 by tension springs 50.

A series of spoked wheels 51 are mounted on a driven shaft 52 and extendthrough cutouts in the discharge runway 45 to engage the bottom edge ofeach bill as it is carried upward by the endless belts 40. The spokedwheels 51 move the bottom edge of each bill onto the discharge runway 45out of the way of a succeeding bill being carried upwardly by theendless belts 40. As shown in FIGS. 1 and 2, the bills in the dischargecompartment project above the top surface of the machine cover 53 andthe corners of the bills are unob scured, so that the denomination ofeach successive bill is displayed as the bill is added to the stack ofbills in the discharge compartment.

As the bills pass beneath the shaft 37 the bills are counted and anyoverlapping or doubled bills are detected. Specifically, a countingswitch actuator 54 projects through an opening 55 in the central runway36 between a pair of the conveyor rollers 38 (see FIGS. 4 and 5). Theswitch actuator 54 is biased to the position where it will projectbetween the conveyor rollers 38 so that the passage of each billconveyed by the rollers 38 will move the switch actuator 54 and close anormally open counting switch 56. A doubles roller 57 is mountedcentrally on the shaft 37 and cooperates, through an opening in thecentral runway 36, with a pair of spaced double detector fingers 58. Thefingers 58 are attached to each side of a lever arm 59 which is keyed toa rotatable stub shaft 60 which also mounts an elongated lever arm 61.The elongated lever arm 61 is disposed to the outside of the side plate11 and is urged by a tension spring 62 to seat against an adjustable setscrew 63. A button actuated doubles switch 64 is mounted on the end ofthe elongated lever arm 61. The button actuator of the doubles switch 64is adapted to engage the end of a switch set screw to hold the buttonactuator depressed so long as the lever arm 61 is seated against the setscrew 63. By adjustment of the set screws 63 and 65, the normal spacingbetween the doubles detector fingers 58 and the doubles roller 57 is setfor the thickness of a single bill. Then, when more than one billthickness passes between the doubles roller 57 and one or both of thedoubles detector fingers 58, the fingers 58 will be depressed to pivotthe lever arm 59 and to also pivot the elongated lever arm 61 todisengage the button actuator of the doubles switch 64 from the switchset screw 65 to thereby actuate the doubles switch 64. It sometimeshappens that a bill in a strap will be folded in half along its width.If such a bill passes through the verifier on the side'of countingsection which includes the counting switch actuator 54, the folded billwill be counted. However, if the folded bill passes through the otherside of the counting section, it will not engage the counting switchactuator 54 and will not be counted. Accordingly, provision is made todetect the presence of the folded bills and this is accomplished by thedoubles detector mechanism. The fingers 58 are each spaced from arespective side frame 11 or 12 a distance less than one half of thelength of a bill. Then, when such a folded bill passes through thecounting section, it will be engaged by one or the other of the fingers58 and will be sensed as a double bill'.

The shaft 37 is driven by the motor 35 through a series of pulleys andbelts, and the shaft 42 may be driven through the endless-belts 40 andmay in turn drive the shaft 52 through meshing gearing, all in a mannerwhich is known in the art of currency counting.

A control panel 66 is hinged to the side frames 11 and 12 by arcuateears 67 which are pinned at their free ends to the side frames 11 and12. The control panel 66 mounts a manually resettable counter 68, adouble s warning light 69 and a doubles reset pushbutton switch 70. Astart switch bar 71 is mounted above the surface of the cover 53 and isadapted, when depressed, to actuate a spring loaded start switch 72.

Referring to the circuit diagram of FIG. 6, the motor 35 is connectedacross a source 73 of alternating current, with a capacitor 74 connectedin parallel with the motor 35. A circuit to energize the motor 35 may becompleted by depressing the start switch bar 71 to close the startswitch 72. However, the motor 35 will not be held actuated upon releaseof the start switch bar 71 unless the stack sensing switch 34 is closedindicating the presence of one or more bills in the receivingcompartment 10. If the stack sensing switch 34 is closed, as soon as thestart switch 72 is closed, a circuit will be completed to the coil 75 ofa first relay having a normally open relay contact 76 in parallel withthe start switch 72. Thus, the mementary closing of the start switch 72will energize the relay coil 75 to close the relay contact 76 tocomplete a holding circuit to the motor 35.

Thus, with bills in the receiving compartment 10, upon depressing thestart switch bar 71, the motor 35 will be energized to drive the feedrollers 19 and 23, the conveyor rollers 38 and pulleys 39 and 41, andthe spoked wheel 51 to remove bills singly from the stack and transportthem through the counting section and into the elevated dischargesection. As each bill passes through the counting section past thecounting switch actuator 54, the counting switch 56 is closed tocomplete a circuit across the source and through the,

counter'68 so that the count of the bill is visually recorded on thecounter 68.

it is necessary to maintain the motor 35 energized until the last billin the stack has beenconveyed into the discharge compartment 44. Sincethe stack switch 34 will open as soon-as the last bill leaves thereceiving compartment and the circuit to the motor 35 would be opened, atime delay circuit is provided to maintain the motor 35 energized for asufficient length of time to insure that the last bill will be fedthrough the counting section and into the discharge compartment 44. Suchcircuit includes a capacitor 77 connected in parallel across the firstrelay coil 75 through a resistor 78 and a diode 79. The capacitor 77 ischarged while the stack switch 34 is closed and the motor 35 energized.When the stack switch 34 opens, the capacitor 77 will discharge througha pair of parallel resistors 80 to continue to energize the first relaycoil 75 and thereby maintain the holding circuit for the motor 35. Whenthe capacitor 77 has discharged to the point that it can no longerenergize the first relay coil 75, the relay contact 76 will open therebyinterrupting the circuit to the motor 35 and the machine will come to ahalt. By this time the last bill will have cleared the machine and havebeen fed into the discharge compartment 44.

Should it develop that bills are conveyed past the counting switchwithout the proper space between the bills such that they overlap, or ifa bill is folded, or if two bills stick together and are conveyed asone, an erroneous count would be recorded. This overlapping,

folded or double condition will be sensed by the doubles detectorfingers 58 and will result in the doubles switch 64 being closed. Thedoubles switch 64 is connected across the source 73 of current at apoint in advance of the start switch 72. Closing of the double switch 64will energize a relay coil 81 of a second relay having a normally openrelay contact 82 in parallel with the doubles detector switch 64 and anormally closed relay contact 83 in series with the start switch 72.Closing of the doubles switch 64 will thus provide a holding circuitthrough the relay contact 82 to maintain the second relay coil 81energized and will also open the circuit involving the start switch 72.The doubles warning light 69 will light on the control panel to alertthe operator to the fact that doubles have passed through the verifierand that the recorded count is in error. Upon the completion of thaterroneous count, it is not possible for the operator to count anotherstack of bills because of the now open relay contact 83 unless theoperator first acknowledges his awareness of the presence of doubles inthe previous count. Thus, it is necessary for the operator to depressthe reset pushbutton switch which will open the circuit to the secondrelay coil 81, extinguish the warning light 69, and permit thesubsequent counting of the stack by returning the normally closed relaycontact 83 to its normal position in which a circuit can again becompeleted to energize the motor 35.

The efficient operation of the currency verifier depends initially onthe ability of the feed rollers 19 and 23 to remove bills one at a timefrom the stack in the receiving compartment, and this in turn depends tpa large extent upon the proper adjustment of the arcuate portion of thefeed runway 13 relative to the lower feed rollers 19. The runwayadjustment assemblies 16 permit proper adjustment to be made in theinitial setup of the machine and also facilitate later adjustments whichmay be required because of wear.

The assemblies 16 each include a shoulder nut 84 which extends throughan opening in the bracket 15 and is threaded about a screw 85 whichextends from the upstanding bracket 17. The shoulder of the nut 84 bearsagainst the bracket 15 and the head of the screw 85 bears against thebracket 17 so that turning each nut 84 upon its respective screw 85 willalter the distance between the brackets 15 and 17 and will thereforechange the horizontal spacing between each end of the arcuate portion ofthe feed runway 13 and the lower feed rollers 19. Once the desiredadjustment has been made, the nut 84 is locked on the screw 85 by meansof a set screw 86 threaded through the center of the nut 84 and bearingagainst the end of the screw 85.'

Dial indicators are provided to facilitate subsequent readjustment.Specifically, a dial plate 87 is secured to the face of each nut 84 by apair of headed screws 88. The dial plate 87 may be rotated on the nutface by loosening the screws 88. The dial plate 87 contains in dicia inthe form of an arrow head 89 and radial lines 90 spaced at forty-fivedegree increments. Once the assemblies 16 have been initially adjustedfor the proper spacing of each side of the feed runway 13 relative tothe lower feed rollers 19, the screws 88 are loosened and the dial plate87 is turned to align the arrow head 89 with a horizontal benchmark 91on the front surface of the bracket 15. The screws 88 are then tightenedto subsequent adjustments are needed they can be carried outsystematically by turning the nut 84 a precise eighth turn at a time. Ifan adjustment in a given direction makes the quality of the bill flowworse, the person making the adjustment can return to the starting pointby realigning the arrow head 89 with the benchmark 91 in preparation forthe next adjustment. Only after the successful readjustment has beenmade will the dial plate 87 be rotated independently of the nut 84 toagain align the arrow head 89 with the benchmark 91.

To summarize the operation of the currency verifier, the operator wouldfirst manually reset the coutner 68 to zero and then load a stack ofbills into the receiving compartment 10. The operator momentarilydepresses the start switch bar 71 and the verifier will then operate toremove the bills singly from the stack and feeds them through themachine into the discharge compartment 44. The operator watches as eachbill is added to the stack in the discharge compartment to insure thatthe bills are all of the same denomination. The count of bills isrecorded on the counter 68 and the verifier stops automatically afterthe last bill has been moved to the discharge compartment. The operatornotes the recorded count and checks it against the supposed quantity ofbills in the stack.

if overlapping, folded or double bills are counted, the

warning light 69 will light and the operator will be unable to count asubsequent stack until he depresses the doubles reset switch 70.

The doubles reset switch 70 may also be employed to stop the operationof the verifier in case of malfunction since it will open all circuitsto the motor 35. Malfunction might occur when worn or torn bills becomejammed in the rollers or belts. Access to the currency conveyingmechanism is obtained by opening the hinged control panel 66 and theoperator can then physically remove any jammed bills.
